ADAPTIVE GENERATION OF A PSEUDO RANDOM NUMBER GENERATOR SEED |
摘要 |
A seed for use in a cryptographic operation for an electronic device is determined by estimating the number of entropy data bits needed to satisfy a predetermined security strength of the cryptographic operation. The estimation is based on an entropy strength of a string of entropy data bits. Entropy strength is a measure of randomness. Furthermore, guiding a determination of the seed differently according to the estimated number of entropy data bits may be performed. |
